Ano Disc Circle w/ Support Ring, 47mm Diameter, 0.1um Pore Size (50/Pk) SKU: 6809-5012

Aluminum Oxide (Anopore) Membrane Filters - 6809-5012

Designed to deliver reproducibility and confidence across critical sample types, the Whatman 6809-5012 provides the filtration consistency that method validation demands. Supporting this capability, a uniform Aluminum Oxide (Anopore) matrix maintains its rated 0.1 cutoff under the pressures and flow conditions encountered during routine laboratory filtration. Controlled production conditions produce membranes with documented pore size distribution and thickness tolerances, supporting method reproducibility across multiple filter lots.

Material Specifications

• Non-fibrous ceramic construction eliminates the shedding and fiber release associated with depth filter media.
• Thermally stable to over 400°C, Anopore membranes withstand sterilization and high-temperature processing without structural change.
• Precisely controlled pore geometry provides sharp molecular weight cutoffs for size-based separation of nanoparticles and macromolecules.
• Anopore Aluminum Oxide membranes feature a unique honeycomb pore structure for precision.
• Packaged without sterilization for applications where downstream sterility is achieved by other means or is not a process requirement.

Multi-site studies where different laboratories must produce comparable data benefit from membranes manufactured to tight specifications, giving you confidence that site-to-site variability is not introduced by the filtration step. Near-zero extractable levels from the ceramic matrix mean your filtrate backgrounds approach the theoretical minimum, supporting the detection limits your trace-level analytical methods require without membrane-derived interference. Make the decision for consistency and reliability, ensuring that your laboratory maintains its reputation for high-quality, error-free output.

• Stack Pre-filtration - Acts as a spacer or depth layer in multi-tier filtration stacks to extend the life of the final downstream membrane.
• Quality Control Testing - Serves as a standard check filter for routine batch purity tests, verifying the absence of visible physical contaminants.
• Vacuum Clarification - Utilized in Buchner funnels to rapidly remove particulates from large-volume batches of non-critical laboratory buffers.
• Air Particulate Sampling - Traps airborne dust and pollen on a positioned open-face filter disc for subsequent microscopic or chemical analysis.
• Gravimetric Analysis - Captures total suspended solids from liquid samples on a weighed disc, ensuring accurate mass measurements for reporting.
• Radiometric Counting - Collects radioactive precipitates for scintillation counting, providing a consistent geometry for accurate data measurement.
